for what it's worth i think there are some people in China who are pretty experienced in this sort of thing, but I have absolutely no idea how to get in touch with them - I have a bunch of GBC games I've been trying to dump with similarly limited success. the only one that worked is Shi Kong Xing Shou. which is pretty cool, but its also an RPG in Chinese, so yknow.

I can't get sound to capture from the card in Windows 7 but the card works fine in OSX so I'll be able to make future videos with both video and sound (and higher video quality too!). Haha, maybe if I can improve my quality of play I can convince SDA to host a speedrun of it ^_-

Edit: Here's a video I captured in OSX, so the sound's intact:
Opening animation
I used lossy compression on it so the video isn't as good, but lossless I get much better video quality on OSX so if I make some more videos they'll be clearer.

Currently it contains the opening demo, the intro stage, and the 8 main stages. There's only one final stage, but it's quite long and I'm having some trouble converting the video. (I got a game over during my recorded attempt anyway so I might just make a different video of it that doesn't waste so much time).

So I was finally able to dump this game! (along with a couple others): http://hhug.me/?post=60
At the moment it's only emulated in the latest nightly builds of mGBA, but that's available for a bunch of platforms so hopefully covers a reasonable number of bases.

Also it's the Chinese-language Taiwanese release, titled Zook Man ZX4, I don't have the English Rockman & Crystal version. Boco, if you're still around and still interested in dumping your copy, let me know!
